Abstract: Provided is a display device including a display panel including a pixel including a first sub-pixel and a second sub-pixel, and a capping layer. The first sub-pixel includes a first pixel transistor disposed on a first pixel circuit area, a first pixel electrode disposed on a first pixel electrode area, a first color filter disposed on the first pixel circuit area while covering the first pixel transistor, and a second color filter disposed on the first pixel electrode area and the first pixel circuit area. The capping layer covers the first color filter and the second color filter, and a first opening is defined in one area of the capping layer, which overlaps the second color filter on a plane.
